ABSTRACT:
In a mold closing unit for use in an injection molding machine for processing synthetic materials a stationary mold carrier and a movable mold carrier are provided. A pressure cylinder comprising a pressure piston serves for building up the locking pressure and at least one piston-cylinder-unit serves for moving the movable mold carrier. The drive piston or drive cylinder are interconnected with the pressure cylinder. The pressure cylinder and the movable mold carrier constitute a motion unit displaceable relative to the stationarily mounted pressure pistons.
